Whether it is important for a baby to fall on the back of the head depends on the baby’s performance. If a child cries due to pain and shock after a fall on the back of the head, and can return to normal after being soothed, without other abnormal manifestations, such as vomiting, headache, etc., and has a good mental state, and can eat, sleep and play normally, it is generally not important and can be closely observed. If a child has vomiting, loss of consciousness or poor mental status, such as drowsiness and abnormal crying after a head injury, he or she should be alerted to the possibility of a large head injury and should be promptly seen by the general surgery or pediatrics department of the hospital, and if necessary, CT and MRI of the head should be performed. In the process of caring for infants and toddlers, special attention should be paid to safety issues. In the process of learning to turn over and walk, bumps and falls are inevitable and parents should pay close attention to avoid accidents.
